Abstract
A packaging assembly for insulation material has a compression chamber and a surge hopper vertically mounted above the compression chamber. An air drawing assembly positioned beneath the compression chamber draws air through the surge hopper and the compression chamber.
Claims20
A packaging assembly suitable for loose fill fibrous insulation material comprising:
- a compression chamber having a perforated bottom wall, the compression chamber being configured to receive and compress the insulation material;
- a surge hopper vertically mounted above the compression chamber, the surge hopper having opposing perforated bottom doors that are configured to collect the insulation material in the surge hopper, and to be opened to disperse the insulation material to the compression chamber;
- and
- an air drawing assembly positioned beneath the compression chamber, the air drawing assembly configured to draw air through the surge hopper and through the compression chamber, thereby maintaining suction on the insulation material in the compression chamber and the surge hopper.

A packaging assembly suitable for loose fill fibrous insulation material comprising:
- a compression chamber having a perforated bottom wall, the compression chamber configured to receive and compress the insulation material;
- and
- a surge hopper vertically mounted above the compression chamber, the surge hopper having opposing perforated bottom doors that are configured to collect the insulation material in the surge hopper, and to be opened to disperse the insulation material to the compression chamber, each bottom door having a long side and a short side, each bottom door pivotably mounted on the long side so that the short side can be pivoted in a downward direction to open the bottom doors.
A packaging assembly suitable for loose fill fibrous insulation material comprising:
- a compression chamber having a perforated bottom wall, the compression chamber configured to receive and compress the insulation material;
- weigh chamber positioned above the compression chamber to supply the insulation material to the compression chamber;
- a surge hopper positioned above the weigh chamber to supply insulation material to the weigh chamber;
- wherein the compression chamber, the weigh chamber, and the surge hopper define the packaging assembly;
- and,
- a single source for withdrawing air from the packaging assembly, the source comprising an air drawing assembly positioned beneath the compression chamber.

A packaging assembly suitable for loose fill fibrous insulation material comprising:
- a compression chamber having a perforated bottom wall and a pivotably mounted compression door, the compression chamber configured to receive and compress the insulation material, and the compression door mounted to pivot toward the bottom wall to a closed position to compress the insulation material;
- a ramming chamber defined by the perforated bottom wall and the compression door when the compression door is pivotably moved to a closed position;
- a ram mounted to move between extended and retracted positions in the ramming chamber for compressing the insulation material;
- and
- an air drawing assembly positioned beneath the bottom wall and configured to draw air through the ramming chamber when the ram is in the extended position, whereby extraneous material is removed from the compression chamber.

A method for packaging insulation material into a compressed package, comprising:
- vertically dispensing the insulation material through a packaging assembly, wherein the packaging assembly comprises:
- a compression chamber having a perforated bottom wall, the compression chamber configured to receive and vertically compress the insulation material;
- a weigh chamber positioned above the compression chamber to supply the insulation material to the compression chamber;
- a surge hopper positioned above the weigh chamber to supply insulation material to the weigh chamber;
- and
- a single source for withdrawing air from the packaging assembly, the source comprising an air drawing assembly positioned beneath the compression chamber;
- and
- horizontally compressing the vertically compressed insulation material into the compressed package of insulation material.
